[PATCH] Fix warnings on fdt_getprop calls

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

There are several calls that get device tree values that pass an
uninitalized length parameter and pedantic static analyzers throw
a warning on this.  Clean this up by initializing the lengths to
avoid this warning.
